Hitherto roller bearings for crank shafts have been mounted by using roller bearings having an internal diameter suficient to allow of the passage of the crank arms of the crank shaft, and interposing between the bearing and the crank shaft tWohalf-rings having a' width greater than that of. the bearing, said two half-rings bein assembled by two bolts; the increase in t e width being necessary in order to accommodate the assembling bolts, That method of mounting has the drawbacks of increasin considerably the length of the crank sha journal, and of not assuring a perfectly I rims a; which serve to hold it rigidly in rigid fixture of the inner roller race of the bearing upon the crank shaft,

The improved method of mounting that forms the ob ect of the present invention does away with the above stated drawbacks.

A practical form of the improved means is illustrated by way of example in the accom anying drawing which is a sectional elevation taken along the axis of the roller bearing. a

The roller bearing proper is constituted in the usual manner, but the outer roller race A of the hearing is made with side place in the crank case; this latter being formed in t parts Go The bore of the inner roller race B is con= constituted by two truncated conical surfaces 6, iig'connectedtogether at their small ends; The'smalleet 'diaeter or double was, eel-m1 an. arena.

to the double truncated conical bore '6, b

of the inner'roller race 18.

By means of bolts F, which act to force the two half rings E, E facing eachother to move the nearer towards each other, perfeet contact is efiected between the crank shaft and the said hall-rings, on the one,

hand,and between these half-rings and th the roller bearin on the other hand.

. The bolts are ocked in any suitable manher for instance by means of a sheet steel plate f having its edges turned up against the heads of the bolts.

Having now particularly described and ascertained thenature oi my said invention and in what manner the same'is to be per formed, I declare that what I claim is:

In a roller hearing for crank shaft journals, the combination-of an inner roller race having two inner truncated conical surfaces connected at their smaller ends, with spacing devices consisting of four half rings, two on either side, the exterior annular surfaces of said rings being beveled to the same angle as the truncated conical surfaces of the race, and clamping bolts parallel to the axis of the crank-shaft journal clamp ing together the oppositely disposed 'mem bers of said rings.
